摘　　要：随着可再生能源的发展与利用,分布式电源开始大量接入配电网,其位置的多样性与容量的提升给配电网带来了稳定性问题。从基本的分布式电源建模入手,构建dq坐标系下分布式电源的电路、控制器模型,解决分布式电源对称模型与配电网不对称电压之间的矛盾;借鉴输电网单相机电暂态方法,提出配电网三相时域仿真方法,给出仿真中关键步骤的处理方法。在测试案例中实现配电网的三相时域仿真,结果验证了理论分析的正确性。With the development and application of renewable energy,lots of DG（Distributed Generation） are connected to the distribution network,which causes the stability problem because of its position diversity and capacity enhancement. Based on the basic model of DG,its circuit and controller models in dq coordinates are built to solve the contradiction between the symmetric DG model and the asymmetric distribution network voltage. Based on the single-phase electromechanieal transient model of transmission network,a three-phase time-domain simulation method is proposed for the distribution network and its key techniques are introduced. The simulative results of test cases prove the correctness of theoretical analysis.
